Float switch
1、Working principle of high temperature float switch
The high temperature float switch moves with the change of liquid level and drives internal switches (such as reed switches and micro switches) through magnetic coupling or mechanical levers to achieve circuit on/off.
High temperature float switch magnetic operation type: The magnetic control element on the switch rod is triggered by the end magnet of the float ball, with no mechanical contact and high reliability;
High temperature float switch mechanical type: When the float is tilted to a specific angle, the internal steel ball presses the spring plate to trigger the micro switch.
Characteristics of high temperature float switch
The high temperature float switch has no complex circuit or power requirements, high temperature float switch have a simple structure, and a long lifespan.
The key parameters of the adjustable high temperature float switch include float diameter, rod length, thread size (such as M10 × 1.5), and blind spot (<12mm).
2、 Adjustable float switch/high temperature float switch type and applicable scenarios
Common classifications of adjustable float switches/PP plastic float switch
high temperature float switch Type Characteristics Application Scenarios
Side mounted adjustable float switch supports side/top installation, adjustable float switch have wide temperature and pressure range, stainless steel material, explosion-proof design, tank level control
Stainless steel float switch is resistant to high temperature and high pressure (316 SS material), and can be installed vertically/horizontally for corrosive media in the chemical and food industries
adjustable float switch can be equipped with dual float balance control, supporting water pump start stop or alarm for household water tower and sewage tank drainage systems
PP plastic float switch economical, acid and alkali resistant water tank, sewage treatment
Adjustable high temperature float switch /PP plastic float switch special type
Mercury float switch: dry contact signal, suitable for 0 ° C-80 ° C environment, avoid collision with pool wall.
3、 Advantages of Adjustable Float Switch /PP plastic float switch Technology
Adjustable float switch has strong anti-interference ability: no electronic circuit, resistant to load impact.
PP plastic float switch installation is flexible: adjustable float switch supports multiple installation methods such as vertical, horizontal, side, and top.
PP plastic float switch maintenance free: adjustable float switch no vulnerable parts such as springs or seals.
4、 PP plastic float switch/adjustable float switch application areas
PP plastic float switch/adjustable float switch industrial scenarios: pump control and liquid level alarm in petrochemical, wastewater treatment, and generator equipment.
PP plastic float switch/PP plastic float switch civilian scenario:
Automatic water filling and overflow prevention control for household water tanks;
Smart home (such as fish tank water level monitoring, bathtub overflow prevention).
5、 PP plastic float switch selection precautions
Liquid properties: The specific gravity (SG) must be greater than the nominal value of the float, otherwise the float cannot float; High viscosity liquids require the selection of large-diameter floating balls.
Environmental requirements: Liquid containing iron filings can adsorb magnets and cause failure; Corrosive media should be selected from stainless steel or PP materials.
Electrical parameters: The load capacity of the dry contact signal (such as 10A/250V) needs to be matched with the equipment power.
